Description

BACKGROUND OF THE DISCLOSURE

1. Field of the Disclosure
The disclosure relates to a spray dispenser. The disclosure further relates to a spray dispenser useful in spraying a liquid on a horizontal surface. The disclosure further relates to a method for spraying a liquid on a surface using the spray dispenser.
2. Description of the Related Art
Spray bottles are commonly used to spray liquid formulations onto surfaces for the purpose of cleaning, polishing, and the like. Spray bottles most commonly take the form of a trigger spray bottle employing a siphon tube to draw out and spray a liquid formulation. The siphon tube typically extends toward the bottom of the bottle.
A problem arises with trigger spray bottles when they are deployed horizontally to spray a liquid formulation on a horizontal surface, such as a floor, carpeting, kitchen counter, or table. In a conventional trigger spray bottle, the siphon tube is vertical. As the liquid formulation in the bottle diminishes in level with use, shifts of the formulation within the bottle may result in the siphon tube being exposed or unsubmerged, which would prevent the trigger sprayer bottle from functioning properly, i.e., from spraying the liquid formulation.
It would be desirable to have a spray dispenser that maintains spraying functionality when the dispenser is deployed horizontally and that would spray substantially all of the formulation from the bottle.

Spray dispenser 40 has a quantity of a liquid formulation 66 with bottle 44 and is shown in FIG. 3 emitting a spray 68 directed to horizontal surface 70. Spray 68 results from squeezing of trigger 48 by hand (not shown).
Another embodiment of the spray dispenser substantially similar to that shown in FIGS. 4 and 5 is generally referenced by the numeral 80. Spray dispenser 80 has a spraying mechanism 82 and a bottle 84. The spraying mechanism 82 has a sprayer 86, a screw cap 92, and an elongated siphon tube 94. Sprayer 85 has a trigger 88 and a nozzle 90. Siphon tube 94 defines a generally U-shaped portion 106 and has a distal end 98. Bottle 94 defines an inverted catchment 100 therein at a front portion 106 of bottle 84. Inverted catchment 100 has a curvilinear member 102. Inverted catchment 100 takes the form of a receptacle and is formed by the confluence of member 102 and adjacent wall portions 107, 108, and 109 of bottle 84. Inverted catchment 100 is situated generally medially with respect to the vertical extension of bottle 84. Distal end 98 of siphon tube 94 is positioned substantially coextensive with the vertical extension of bottle 84 and within inverted catchment 100.
Another embodiment of the spray dispenser of the present disclosure is shown in FIGS. 6 and 7 and is generally referenced by the numeral 110. Spray dispenser 110 has a spraying mechanism 112 and a bottle 114. The spraying mechanism 112 has a sprayer 116, a screw cap 122, and an elongated siphon tube 124. Sprayer 115 has a trigger 118 and a nozzle 120. Siphon tube 124 defines a generally U-shaped portion 126 and has a distal end 128. Bottle 114 defines an inverted catchment 130 therein at a front portion 136 of bottle 114. Inverted catchment 130 has a horizontally disposed first member 132 and a vertically disposed second member 134, which intersect each other at a right angle. Inverted catchment 130 takes the form of a receptacle and is formed by the confluence of members 132 and 134 and adjacent wall portions 137, 138, and 139 of bottle 114. Inverted catchment 130 is situated generally medially with respect to the vertical extension of bottle 114. Distal end 128 of siphon tube 124 is positioned substantially coextensive with the vertical extension of bottle 114 and within inverted catchment 130.
Inverted catchments of the spray dispensers of the present disclosure are preferably structurally bounded such that liquid infiltration occurs only through an open bottom. When the spray dispenser is deployed substantially horizontally for purpose of applying a liquid formulation to a horizontal surface, the liquid formulation will flow into the inverted catchment for withdrawal through the siphon tube.
The inverted catchment may be situated anywhere along the inner wall in the bottle but is preferably situated proximal to the bottom of the bottle. The catchment is preferably situated within about 60% and more preferably about 10% to about 30% along the length of the vertical extension of the bottle taken from the reference point of the bottom of the bottle to the top of the cap. Further preferably, the portion of the members and/or walls that form the inverted catchment that is uppermost (with reference from the bottom of the bottle to the top of the cap) along the vertical extension of the bottle is also at up to 60% and more preferably about 10% to about 30% (e.g., first member 32 in FIGS. 1 and 2, the confluence of curvilinear member 102 and wall portion 107 in FIG. 4, and first member 132 in FIGS. 6 and 7).
The elongated siphon tube extends from the spraying mechanism, e.g., the trigger head, and is open at its distal end. When the trigger of the spraying mechanism is actuated, suction occurs within the siphon tube and liquid from within the bottle is drawn therefrom through the open distal end and forced out of the nozzle. The siphon tube defines a generally U-shaped portion proximal to its distal end. In some embodiments, the “bend” or location/section of curvature in the siphon tube will be in the last one-half or last one-third of the length thereof as in the embodiments depicted herein. The distal end is positioned or situated within the inverted catchment so as to access the liquid formulation when the catchment is filled during horizontal deployment of the spray dispenser. The farther the distal end extends into the inverted catchment and the closer it extends to the inner wall of the bottle, the greater the proportion of liquid formulation that can be sprayed from within the bottle. In some embodiments, such as the embodiments depicted herein, the portion of the siphon tube within the inverted catchment will be substantially vertical, i.e., within about 45° of vertical and more typically about 30° of vertical. In a preferred embodiment, the elongated siphon tube will be of length sufficient for the distal end of the siphon tube to abut or substantially abut the inner wall of the bottle within the inverted catchment so that the distal end will be static or immobilized within the inverted catchment (for example, the embodiment in FIGS. 6 and 7).
The components of the spray dispenser, including the bottle, inverted catchment, and siphon tube, can be formed from any conventional material but will typically be formed from a thermoplastic. Useful thermoplastics include, for example, polyethylene, polypropylene, polyester, and vinyl chloride. When a thermoplastic is employed, the components can be formed by any method known in the art, such as blow molding, injection molding, extrusion, and stamping. The thermoplastic can be transparent, translucent, or opaque as desired. The embodiments depicted herein employ a transparent thermoplastic so that the internal components of the bottle of the spray dispenser will be apparent in the several views. Most typically, commercial embodiments will employ an opaque thermoplastic.
It should be understood that the foregoing description is only illustrative of the present disclosure. Various alternatives and modifications can be devised by those skilled in the art without departing from the disclosure. Accordingly, the present disclosure is intended to embrace all such alternatives, modifications and variances that fall within the scope of the appended claims.
